## Quick reference

| Question                             | What to expect                                                                                                        |
| ------------------------------------ | --------------------------------------------------------------------------------------------------------------------- |
| **Which projections are confirmed?** | AP and lateral thoracic spine projections.                                                                            |
| **Can users try other projections?** | **Yes.** These are confirmed examples. Other projections may be possible when the simulated setup supports them.      |
| **What anatomy is included?**        | Thoracic vertebrae, scapulae, ribs 1-10, sternum, lumbar spine, and pelvis.                                           |
| **What setup is used?**              | Table bucky workflow with recumbent patient positioning.                                                              |
| **What movement is included?**       | Patient lateral rotation onto the right side for decubitus positioning plus craniocaudal and mediolateral adjustment. |
| **What bone variations exist?**      | Healthy bone version.                                                                                                 |
| **Known limitation**                 | Prone or erect thoracic spine positioning is not supported. Vertebrae have limited trabecular bone detail.            |

<Card title="Projection expectations" icon="circle-info" type="note">
  The projections listed on this page are confirmed examples for this simulation module. They do not define the full limit of what can be attempted. The simulator creates an image from the selected anatomy, patient position, joint movement, detector setup, tube position, collimation, and exposure settings, so other projections may be possible when the setup supports them.

## Bone variations

* Healthy bone version

## Known limitations

The T-spine simulation is limited to recumbent patient positioning. This restricts projections that require prone or erect positioning. The vertebrae also have a low presence of trabecular bone structures, which may limit radiographic realism when evaluating bone quality and internal architecture.
